Good article by Yahoo! Sports' Jason Cole on this. He interviews Mike Martz and an unnamed offensive coordinator on the future of Jay Cutler, Matt Leinart and Vince Young.

Money quote on young buy the offensive coordinator:

Martz was being polite. The kid can?t throw. He just can?t. Worse, he still can?t read coverages. The Tennessee passing game with him is either throw it underneath or throw it deep because he?s scary on the mid-range stuff. He has no touch on half his throws and no idea where the defenders are on the other half ? I?m being brutally honest and this is hard because he?s not a bad guy, but he?s soft and he doesn?t understand how much work he has to do to get better.

When he was at Texas, they just let him improvise all the time. He?s such a great athlete, he could get away with anything. Just run around until he made a play. In this league, you can?t do that. That stuff about how coaches should draw up a whole new offense for him is crap. The defenses are too good in this league. In college, you have about four games every year where you really have to be sharp. In this league, you have to be sharp every game.
